datasets: move initial file reading to rust
In a recent warning reported by scan-build, datasets were found to be
using a blocking call in a critical section.
datasets.c:187:12: warning: Call to blocking function 'fgets' inside of critical section [unix.BlockInCriticalSection]
187 | while (fgets(line, (int)sizeof(line), fp) != NULL) {

5 warnings generated.
These calls are blocking in the multi tenant mode where several tenants
may be trying to load the same dataset in parallel.
In a single tenant mode, this operation is performed as a part of a
single thread before the engine startup.
In order to evade the warning and simplify the code, the initial file
reading is moved to Rust with this commit with a much simpler handling
of dataset and datarep.
